Oibò, dove sbaglio?
image_mc.onRelease non traccia nulla... perchè?!?!

codice:
class ImageFocus{
		// properties
	// -----------------------------------------------------------------------------------
	private var image_mc:MovieClip;
	// constructor
	// -----------------------------------------------------------------------------------
	public function ImageFocus(target:MovieClip, imm:String) {
	trace("costruttore di ImageFocus")
	image_mc = target.createEmptyMovieClip("image_mc_istanza", 1)
	image_mc.loadMovie(imm)
	image_mc.onRelease=function(){
		trace("lascia")
	}
	}
}
